Longer journey times by road, bus and train are likely - and there could be power cuts in some areas.

The forecast says: "Frequent, heavy hail and snow showers are expected through Sunday and will lead to snow accumulating on many surfaces. Longer journey times by road, bus and train services are likely while some vehicles could become stranded.

"Ice is likely to form on untreated pavements, cycle paths and roads leading to some injuries from slips and falls. Power cuts may occur and other services, such as mobile phones, may be affected."

The worst affected areas will be Sheffield and York, according to the forecasts, with temperatures in Leeds hitting a maximum of four degrees but snow being slightly less likely.
